Indoor purple banana - Marshydro TS1000

The plants are starting to recover from the N excess 2 weeks ago, this delayed a bit the starting of flower from some plants but im sure that the rest of flowering will be ok, i gave only water this week and applied a small amount of guanokalong nutrients as these are slowly absorbed to ensure the plant continues to receive some nutrients until next 2 weeks when we will start to give some extra PK
